A first air groove communicated with the vertical groove is formed in the mounting column.

The upper surface of the base is rotatably provided with a mounting ring which is coincident with the axis of the base, two mounting rods are vertically and fixedly mounted on the mounting ring, and a strip-shaped annular air bag is vertically and fixedly mounted on the mounting rods. And a second air groove communicated with the annular air bag is formed in the mounting ring. A third air groove communicated with the second air groove and the first air groove is formed in the base. An outer gear ring which is coincident with the axis of the mounting ring is fixedly mounted on the mounting ring. A first motor is fixedly installed on the outer side wall of the base through a motor base in a vertical mode, and an incomplete gear meshed with the outer gear ring is fixedly installed on an output shaft of the first motor in a horizontal mode.

When the magnet block 24 reaches the upper part of the magnet strip 25, the lifting block 21, the third motor 22, the grinding mechanism 23 and the magnet block 24 ascend, the grinding mechanism 23 extends into the gap between two adjacent grids of the top cover, and the grinding mechanism 23 is driven by the third motor 22 to grind and polish the surfaces of the grids. After the magnet block 24 leaves the upper part of the magnet strip 25, the lifting block 21, the third motor 22, the grinding mechanism 23 and the magnet block 24 descend and return to the original position, and the grinding mechanism 23 leaves the gap between two adjacent grids of the top cover. At the moment, the mounting ring 9 continues to rotate to drive the mounting rod 10, the annular air bag 11 and the top cover to synchronously rotate, the polished grating leaves the upper part of the polishing mechanism 23, and the grating to be polished reaches the upper part of the polishing mechanism 23. And repeating the steps, and taking down the top cover after finishing polishing all the grids.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
